You've seen theteasers, now bask in greatness of the first full trailer for Doctor Who Season 8, featuring our best look yet at Peter Capaldi as the Twelfth Doctor.

Tons of great action to be had here, obviously. Explosions abound, the synthetic crackle of a Dalek's voice declares that "life returns," and a T. rex marauds before the Houses of Parliament. There's even a glimpse of Capaldi riding horseback in his pajamas. But just as thrilling are the trailer's darker thematic elements (which Capaldi references rather explicitly as a point of destination for the season). We're especially excited to see this Doctor grapple with valuations of good and evil as he comes to terms with his new identify. Capaldi definitely has a gravitas about him that we haven't seen from more recent incarnations of The Doctor (Those eyes! See them smolder!) – we can't wait to see how he fills the role.
